Underwater Heads-up Display

ABSTRACT

Various embodiments associated with a heads-up display capable of functioning while underwater are described. An underwater mask can have a segment that a diver sees through and this segmented can be augmented with various portions that disclose information to the diver. These portions can relate to the diver herself or relate to other information such as the location of a source transmitting a signal. With these portions the diver can quickly learn about important information and act on that information.

GOVERNMENT INTEREST

The innovation described herein may be manufactured, used, imported,sold, and licensed by or for the Government of the United States ofAmerica without the payment of any royalty thereon or therefore.

BACKGROUND

To dive underwater, a diver may employ different pieces of equipment.One example piece of equipment can be a breathing apparatus thatincludes an oxygen tank, hoses, and a mouthpiece. This breathingapparatus can enable the diver to stay underwater for a significantperiod of time. However, employment of the breathing apparatus canprovide drawbacks. In one example, the driver cannot verballycommunicate due to the mouthpiece and the fact that the diver isunderwater. Therefore, communication for the diver while underwater canbe limited. This can be a serious situation based on circumstances, suchas when emergency circumstances occur.

SUMMARY

In one embodiment, an underwater mask comprises an eyewear element anddisclosure component. The eyewear element can be configured to besubstantially transparent. The disclosure component can be configured tocause disclosure of a heads-up display upon the eyewear element whilethe eyewear element is submerged underwater.

In one embodiment, a system comprises an access component, aconfiguration component, and a non-transitory computer-readable medium.The access component can access a data set that pertains to anunderwater diver. The configuration component can configure a heads-updisplay in accordance with the data set, where the heads-up display, asconfigured, is disclosed upon an eyewear element of the underwaterdiver. The non-transitory computer-readable medium can retain at leastone instruction associated with the access component, the configurationcomponent, or a combination thereof.

In one embodiment, a system comprises an access component, aconfiguration component, a disclosure component, and a housing. Theaccess component can access a data set that pertains to an underwaterdiver. The configuration component can configure a heads-up display inaccordance with the data set; where the heads-up display, as configured,is disclosed upon an eyewear element of the underwater diver. Thedisclosure component can cause disclosure of the heads-up display, asconfigured, upon the eyewear element while the eyewear element issubmerged underwater. The housing can retain the access component, theconfiguration component, and the disclosure component such that theaccess component, the configuration component, and the disclosurecomponent function without substantial adverse impact when submergedunderwater at a distance of about 50 meters

FIG. 1 illustrates one embodiment of an environment in which a receiver110 receives a signal 120 from a source 130 that is processed by aprocessor unit 140. The source 130 can emit the signal 120 that isreceived by the receiver 110. In one example, the source 130 can be apiece of equipment of a diver and the signal 120 can be a distresssignal that communicates positional information of the source 130. Thedistress signal can be emitted by the diver by pressing a button,emitted when a condition is met (e.g., when the diver becomesunconscious determined by way of a biometric sensor), etc. In oneexample, the signal 120 can be a passive signal from which locationand/or direction information can be ascertained. The source 130 canselect a signal type (e.g., distress signal when an injury occurs, lostsignal when a diver becomes disoriented on his location, etc.) and emitthe signal 120 of that type.

The receiver 110 can receive the signal 120. Acoustic energy of thesignal 120 can couple with an antenna array of the receiver 110 as partof this reception. The receiver 110 can be a hardware device that is alow-profile telescopic mast. In one example, the mast can be cylindricalthat when fully-retracted can be about 4 inches and when fully-extendedcan be about 36 inches. With this example, the receiver 110 can have apointer tip integrated with an antenna to receive the signal 120. Thepointer tip can obtain the signal 120 and the signal 120 can betransferred down a conductive surface of the mast and then sent to theprocessor unit 140 (e.g., that is separate from the receiver 110, thatis at least partially part of the receiver 110, etc.).

FIG. 2 illustrates one embodiment of a system 200 comprising a radiofrequency power detector 210, a voltage-to-frequency converter 220, afrequency-to-voltage converter 230, and a microcontroller unit 240. Inone embodiment, the processor unit 140 of FIG. 1 can comprise at leastpart of the system 200. The system 200 can be divided into two parts—areceiver portion 250 that can be integrated into a handle of thereceiver 110 of FIG. 1 and a body portion 260 that can be integratedinto bodywear of the diver (e.g., integrated into a palm section of awetsuit glove).

The radio frequency power detector 210 and the voltage-to-frequencyconverter 220 can integrate into the receiver portion 250. The signal120 that is received by the receiver 110 of FIG. 1 can be a radiofrequency (time-variant) signal that is at a high frequency. The radiofrequency power detector 210 (e.g., envelope broadband detector) canconvert the signal 120 to a direct current (DC) signal 270 with aspecific voltage value proportional an acoustic signal power input ofthe signal 120. The voltage-to-frequency converter 220 can take the DCsignal 270 with the specific voltage value and convert it to a timevariant signal, but at a lower frequency than the initially receivedradio frequency to become the low frequency (LF) signal 280. Thereceiver portion 250 can transmit the lower frequency time variantsignal (LF signal 280) by way of a transmission coil to the body portion260.

The body portion 260 can receive the lower frequency time variant signal(LF signal 270) by way of a pick-up coil. The frequency-to-voltageconverter 230 can convert the lower frequency time variant signal (LFsignal 270) back to the DC signal 270 with the specific voltage value.The microcontroller unit 240 can then process the DC signal 270 toidentify the specific voltage value and then use the specific voltagevalue (e.g., to determine the location of the source 120 of FIG. 1). Asan alternative to the microcontroller unit 240 an analog unit can beemployed in the body portion 260 to process the DC signal 270.

In one example, the signal 120 can indicate position information of thesource 130 of FIG. 1. The specific voltage value selected by the radiofrequency power detector 210 can correlate to the position information.The lower frequency time variant signal (LF signal 280) can directlycorrespond to the specific voltage value (e.g., determined by way of alook-up table) for use by the converters 220 and 230. Therefore, by wayof the specific voltage value, the microcontroller unit 240 can receivethe correct position information. The microcontroller unit 240 can usethe specific voltage value to communicate the position information ofthe source 130 of FIG. 1 to the diver (e.g., by way of a mask of thediver).

FIG. 3 illustrates one embodiment of a system 300 comprising a firstconversion component 310, a second conversion component 320, and atransmitter 330. The first conversion component 310 can be configured toconvert a high frequency (HF) alternating current (AC) signal 340 (e.g.,the signal 120 of FIG. 1 as an acoustic location signal) to the DCsignal 270. A voltage value (e.g., the specific voltage value) of the DCsignal 270 can correspond to a frequency value of the HF AC signal 340.In one example, the radio frequency power detector 210 of FIG. 2functions as the first conversion component 310.

The second conversion component 320 can be configured to convert the DCsignal 270 to a LF AC signal 350. In one embodiment, this conversion cantake place through use of a voltage control oscillator. The frequencyvalue of the LF AC signal 350 can correspond to the voltage value of theDC signal 270. Therefore, the LF AC signal 350 can communicate the sameinformation as the HF AC signal 340, but at a different frequency (at alower frequency). In one embodiment, a look-up table can be employed forconversion between DC and AC by either or both of the conversioncomponents 310 and 320. In one embodiment, the voltage-to-frequencyconverter 220 of FIG. 2 can function as the second conversion component320.

The transmitter 330 (e.g., that is part of the voltage-to-frequencyconverter 220 of FIG. 2) can be configured to transmit the LF AC signal350 to a near-field receiver 360 (e.g., that is part of thefrequency-to-voltage converter 230 of FIG. 2). The first conversioncomponent 310, the second conversion component 320, the transmitter 330,the near-field receiver 360, or a combination thereof can function whileunderwater and/or be resident upon a collection unit (e.g., the receiver110 of FIG. 1). In one example, the first conversion component 310, thesecond conversion component 320, and the transmitter 330 can beencompassed in the handle of the receiver 110 of FIG. 1 while thenear-field receiver 360 (e.g., the body portion 260 of FIG. 2 thatincludes the near-field receiver 360) can be encased in a plasticcapsule that is part of bodywear of a diver (e.g., attached to a part ofa wetsuit).

The transmitter 330 can employ a transmission coil to transmit the LF ACsignal 350 to the near-field receiver 360. The near-field receiver 360can employ or be a reception coil to receive the LF AC signal 350 fromthe transmitter 330. The transmission coil and reception coil can workinductively to communicate the LF AC 350 from the transmitter 330 to thenear field receiver 360.

FIG. 4 illustrates one embodiment of a system 400 comprising the firstconversion component 310, the second conversion component 320, thetransmitter 330, and a direction component 410. The direction componentcan be configured to determine a direction of the source 130 of FIG. 1of the signal 120 of FIG. 1. This can be when the signal 120 of FIG. 1is the HF AC signal 340 of FIG. 3. The HF AC signal 340 of FIG. 3 cancommunicate the direction of the source 130 of FIG. 1. Thiscommunication can be direct communication (e.g., expressly communicatethe information) or be indirectly communicated such that the directioncan be determined from signal information.

The direction component 410 can determine the direction through variousmanners. In one example, the direction component 410 can be configuredto determine the direction through time-direction of arrival analysis.In one example, the direction component 410 can be configured todetermine the direction through omni-directional transpondence analysis.More detail regarding function of determining direction is addressedbelow with the discussion for FIG. 8.

FIG. 5 illustrates one embodiment of a system 500 comprising the firstconversion component 310, the second conversion component 320, thetransmitter 330, and a collection component 510. The collectioncomponent 510 can be configured to collect the HF AC signal 340 of FIG.3 prior to conversion to the DC signal 270 of FIG. 3. Example type ofcollection can include actively obtaining the HF AC signal 340,passively receiving the HF AC signal 340, accessing the HF AC signal 340from storage, etc. The collection component 510 can collect the HF ACsignal from a repeater 610 discussed below and/or the source 130 of FIG.1.

FIG. 6 illustrates one embodiment of an environment 600 comprising thesource 130, the repeater 610, and an obtainment unit 620. The obtainmentunit 620 can comprise the receiver 110 of FIG. 1 and/or the processorunit 140 of FIG. 1 (and in turn aspects of FIGS. 2 and 3). The source130 can be under a body of water with a water level of 630 and transmitthe signal 120 that is of interest to the obtainment unit 620. However,the obtainment component 620 may not receive the signal 120 directlyfrom the source 130. This can be due to various factors, such as anobstruction blocking direction communication between the source 130 andthe obtainment unit 620 or the source 130 and obtainment unit 620 beingconfigured to communicate directly with a central unit (e.g., therepeater 610).

The repeater 610 can be a satellite or other object (e.g., communicationdevice on an airplane) that propagates the signal 120 and/or producesthe signal 120 (e.g., in response to instruction from the source 130).In one embodiment, the repeater 610 repeats the signal 120 from thesource 130 to the obtainment unit 620. In one embodiment, the source 130sends the signal 120 in an encrypted manner so as to not have itscontent ascertained by an unintended force. The repeater 610 candecipher the signal 120, re-encrypt the signal 120 (e.g., using the sameencryption as from the source 130 to the repeater 610 or a differentencryption), and send the signal 120 re-encrypted to the obtainment unit620. In one example, the source 130 can be of one military force whilethe obtainment unit 620 is of another friendly force. While the forcesare friendly, they may not wish for the other to know their encryptionalgorithms and therefore the repeater 610 can function to maskencryption details from the forces.

FIG. 7 illustrates one embodiment of a system 700 comprising a digitalconversion component 710, an analog conversion component 720, and anemitter 730. The digital conversion component 710 can convert the HF ACsignal 340 (e.g., a distress signal) to the DC signal 270. A voltagevalue of the DC signal 270 can correspond to a frequency value of the HFAC signal 340. The frequency value indicates a direction of the source130 of FIG. 1 of the HF AC signal 340. The analog conversion component720 can convert the DC signal 270 to the LF AC signal 350. A frequencyvalue of the LF AC signal 350 can correspond to the voltage value of theDC signal 270 and thus in turn correspond to the frequency value of theHF AC signal 340.

The emitter 730 can emit the LF AC signal 350 to the near-field receiver360 when the emitter 730 and the receiver 360 are underwater. Thenear-field receiver 360 can processes the LF AC signal 360 to determinethe direction (e.g., the direction relative to the receiver 360, thedirection relative to a view position of a diver, etc.). The emitter 730can employ an emission coil to emit the LF AC signal 350 to thenear-field receiver 360 while the near-field receiver 360 can employ areception coil to receive the LF AC signal 350 from the emitter 730. Thenear-field receiver 360 can convert the LF AC signal 350 to the DCsignal 270 and employ the DC signal 270 to determine the direction. Thenear-field receiver 360 of can be part of the body portion 260 of FIG. 2and can cause information based on the direction to be displayed by wayof an underwater mask of the diver.

FIG. 8 illustrates one embodiment of a system 800 comprising the digitalconversion component 710, the analog conversion component 720, theemitter 730, an acquisition component 810, and a housing 820. Theacquisition component 810 can acquire the HF AC signal 340 of FIG. 7.Example implementations by which this acquisition of the acquisitioncomponent 810 can occur can be through radio frequency based monopulsebeamforming (e.g., use of a single phase center antenna with anassumption of varying amplitude and constant phase) or phase monopulsebeamforming (e.g., use of multiple antennas separated by a distance dwith an assumption of varying phase and constant amplitude). Theacquisition component 810 can use a sum-channel Σ and azimuthdifference-channel Δ_(az) as part of beamforming. The difference-channelcan indicate an azimuth direction of the signal 120 of FIG. 1 while thesum-channel can indicate signal amplitude. For phase based monopulsebeamforming a path length difference for the signal 120 of FIG. 1 atazimuth angle θ to reach the receiver 110 of FIG. 1 can be defined byΔR=d sin(θ). The time-difference-of-arrival (TDOA) for the signal 120 ofFIG. 1 at an arriving angle θ off an antenna broadside can be defined asδT=d sin(θ)/c, where c is the speed of light (3×10⁸ m/sec). Bothamplitude and phase monopulse beamforming can measure the Δ_(az)/Σvoltage ratio in order to estimate the error angle δ_(θ). Subsequently,this estimate can be used by the direction component 410 of FIG. 4 todetermine the direction of arrival for the signal 120 of FIG. 1.

The housing 820 can retain the acquisition component 810, the digitalconversion component 710, the analog conversion component 720, theemitter 730, at least one other component or other item (e.g.,converter) disclosed herein, or a combination thereof. The housing 820can be configured for use underwater such that a component retained bythe housing 820 can function while underwater. The housing 820 can be ofa shape for retention within the palm of a diving glove. In one example,the housing 820 can be a plastic handle of the receiver 110 of FIG. 1that can be gripped by the diving glove. The near-field receiver 360 ofFIG. 7 can be resident upon a diving glove. For the near-field receiver360, being resident on the diving glove can include being in a palmarea, wrist area, finger area, thumb area, etc.

FIG. 9 illustrates one embodiment of a system 900 comprising an eyewearelement 910 and a disclosure component 920. The system 900 can be partof an underwater mask that can be considered in at least some instancespart of the body portion 260 of FIG. 2. Example underwater masks includea full-head mask, a full-face mask, an eye cover element (e.g., thatdoes not cover nose or mouth), goggles, a SCUBA (self-controlledunderwater breathing apparatus) mask, a mask appropriate for deep seadiving, or a mask appropriate for snorkeling.

The mask can comprise the eyewear element 910 and the eyewear element910 can be substantially transparent. In one example, the eyewearelement 910 can be made of a plastic or other compound that can haveinformation displayed such that a wearer can see through at least partof the eyewear element 910, but the wearer can also be presented withinformation by way of the eyewear element 910. The disclosure component920 can be configured to cause disclosure of a heads-up display upon theeyewear element 910 while the eyewear element 910 is submergedunderwater. The disclosure component 920 can be part of the mask in thatit is part of a strap that keeps the mask on a head of the diver, thedisclosure component 920 can physically connect to the eyewear element910 to cause such disclosure, etc. In one embodiment, a housing (e.g.,that is functionally equivalent to the housing 820 of FIG. 8) canconfigured to retain the disclosure component 920 such that thedisclosure component 920 functions without substantial adverse impactwhen submerged about 350 meter or less underwater. Thus, whileunderwater the eyewear element 910 can cause display of the heads-updisplay.

FIG. 10 illustrates one embodiment of a heads-up display 1000. Theheads-up display 1000 is an example heads-up display that can bepresented upon the eyewear element 910 of FIG. 9. The heads-up display1000 can have various portions that communicate information whilenon-portion areas can allow a wearer to see outside of the eyewearelement 910 of FIG. 9. While distinct portions are shown, it is to beappreciated by one of ordinary skill in the art that portions may not bedistinct with one another, different portions can be active at differenttimes, and that portions may overlap.

In one embodiment, the heads-up display 1000 comprises a directionalportion 1010 configured to indicate a location of the source 130 of FIG.1 relative to a direction the wearer of the eyewear element 910 of FIG.9 faces and/or a direction of an antenna (e.g., of the receiver 110 ofFIG. 1) that receives the signal 120 of FIG. 1. In one embodiment, thedirectional portion is light-emitting diode display integrated into theeyewear element 910 of FIG. 9. The directional portion 1010 can indicateto the wearer (e.g., the diver) where to travel in order to reach thesource 130 of FIG. 1 and/or give an indication of the location of thesource 130 of FIG. 1 so the source 130 of FIG. 1 can be avoided. In oneembodiment, the directional portion 1010 can comprise multiple lights(e.g., five lights) that are green, yellow, or red depending on how thedirection of the wearer matches the location of the source 130 ofFIG. 1. In one embodiment, the multiple lights can have a light sequencethat indicates how the direction of the wearer matches the location ofthe source 130 of FIG. 1 as well as how to improve a location to becomecloser to the source 130 of FIG. 1 (e.g., flashing the right or leftlights with regard to which way to turn to more quickly reach the source130 of FIG. 1). In one embodiment, the directional portion 1010 cancommunicate text.

In one embodiment, the heads-up display 1000 comprises a warning portion1020 configured to indicate an equipment error for equipment employed bythe wearer of the eyewear element 910 of FIG. 9 and/or of another (e.g.,another diver of a party of the wearer) as well as other error types(e.g., dangerous depth warning). The warning portion 1020 can be aflashing light to indicate existence of the equipment error. The warningportion 1020 can be more detailed such as a text display on what pieceof equipment is in error, specificity on the error, etc.

In one embodiment, the heads-up display 1000 comprises an identificationportion 1030 configured to identify a specific transmitter associatedwith a specific signal received by a reception component (e.g., thereceiver 110 of FIG. 1). In one example, multiple divers can be part ofa dive team such as ‘diver A’, ‘diver B’, and ‘diver C.’ Diver C canbecome injured and press a distress button causing a broadcaster (e.g.,the source 130 of FIG. 1) on their body or elsewhere (e.g., the repeater610 of FIG. 6) to send a distress signal (e.g., the signal 120 of FIG.1). As part of this distress signal an indication can be provided thatdiver C is distressed and diver C's name can be displayed in theidentification portion 1030 while the warning portion 1020 flashes.

In one embodiment, the heads-up display 1000 comprises a distanceportion 1040 configured to indicate a distance of the source 130 of FIG.1 relative to a location of the wearer of the eyewear element 910 ofFIG. 9. The distance can be longitudinal distance and/or latitudinaldistance. The distance portion 1040 can include a directional arrow toindicate if the wearer is above/below the source 130 of FIG. 1 or toindicate if the source 130 of FIG. 1 is moving (e.g., sinking) Thedistance portion can also disclose distance information for the wearersuch as displaying current depth.

In one embodiment, the heads-up display 1000 comprises a level portion1050 configured to disclose a level of an oxygen level for a tank set ofa wearer of the eyewear element 910 of FIG. 9. The oxygen level caninclude an amount of oxygen remaining in the tank set, an expectedduration of proper submersion in view of the amount of oxygen remaining,etc. Different portions can integrate into singular portions, such asthe level portion 1050 integrating with the warning portion 1020 suchthat when the level portion reaches or surpasses a certain threshold,the level portion 1050 can flash and thus also function as the warningportion 1020.

The heads-up display 1000 can comprise other portions as well. In oneexample the heads-up display 1000 can comprise a positional portionconfigured to positional information for the wearer of the eyewearelement 910 of FIG. 9 (e.g., a depth portion configured to indicate adepth level of the underwater diver, a compass point with degreeindication, etc.). This positional portion can replace or be part of thedistance portion 1040. In one example, information integrated with thereceiver 110 of FIG. 1 can have a portion, such as a direction that anantenna of the receiver 110 of FIG. 1 is facing. While shown as distinctportions, one physical area can be used for multiple portions (e.g.,yellow and green for lights of the directional portion 1010 are used fordirection while the lights turning red indicate a warning as the warningportion 1020 would indicate).

Further, the heads-up display 1000 can comprise a physical vital portionconfigured to disclose physical vital information about a person (e.g.,one or more physical vital), such as physical vital information of thediver wearing the mask and/or the physical vitals of a distressed diver.Example physical vitals can comprise heart rate, level of consciousness,breathing rate, body temperature, etc. In one example, the physicalvital portion can be configured to be part of the heads-up display 1000in a limited circumstance, such as when a threshold is met (e.g., thedistressed diver becomes unconscious). The physical vital portion can bepart of the identification portion 1030 (e.g., when addressing physicalvital information about a person associated with the specifictransmitter).

FIG. 11 illustrates one embodiment of an access component 1110, aconfiguration component 1120, and a non-transitory computer-readablemedium 1130. The access component 1110 can access a data set thatpertains to an underwater diver (e.g., the wearer). This data set can bethe oxygen level, information about the signal 120 of FIG. 1 (e.g.,location of the source 130 of FIG. 1 as indicated by the signal 120 ofFIG. 1 or the DC signal 270 of FIG. 2), etc. The configuration component1120 can configure the heads-up display 1000 of FIG. 10 in accordancewith the data set. The heads-up display 1000 of FIG. 10, as configured,can be disclosed upon the eyewear element 910 of FIG. 9 of theunderwater diver. This configuration can include determining placementof different portions, determining information for inclusion ofdifferent portions, selecting an attribute of different portions (e.g.,color of text in the portions based on darkness that surrounds thediver), etc. The non-transitory computer-readable medium 1130 can retainat least one instruction associated with the access component 1110, theconfiguration component 1120, at least one other component disclosedherein, or a combination thereof.

In one embodiment, the system 1100 can comprise the disclosure component920 of FIG. 9. The disclosure component 920 of FIG. 9 can causedisclosure of the heads-up display 1000 of FIG. 10, as configured, uponthe eyewear element 910 of FIG. 9. This disclosure can occur while theeyewear element 910 of FIG. 9 is submerged underwater. In one example,the configuration component 1120 can obtain information from themicrocontroller unit 240 of FIG. 2 while underwater (e.g., theconfiguration component 1120 accesses information from themicrocontroller unit 240 of FIG. 2, the configuration component 1120 ispart of the microcontroller unit 240 of FIG. 2, etc.). The configurationcomponent 1120 can process this information and determine what should beincluded on the heads-up display 1000 of FIG. 10, how content for theheads-up display 1000 of FIG. 10 should be arranged, etc. In accordancewith the determination of the configuration component 1120 thedisclosure component 920 of FIG. 9 can cause disclosure of the heads-updisplay 1000 of FIG. 10 (e.g., cause disclosure of the portions1010-1050 of FIG. 10). The system 1100 can function in a feedback mannersuch that as information is updated (e.g., the diver's physical positionchanges relative to the source 130 of FIG. 1, new information aboutdiving equipment is learned, etc.) the configuration component 1120 candetermine an update for the heads-up display 1000 of FIG. 10. In turn,the disclosure component 920 of FIG. 9 can propagate this update (e.g.,when oxygen level goes from 97% to 96% the level portion 1050 of FIG. 10can reflect this change).

In one embodiment, the system 1100 comprises the housing 820 of FIG. 8.The housing 820 of FIG. 8 can be configured to retain the disclosurecomponent 920 of FIG. 9, the access component 1110, the configurationcomponent 1120, the non-transitory computer-readable medium 1130, atleast one other component or other item disclosed herein, or acombination thereof. The retention can be such that the disclosurecomponent 920 of FIG. 9, the access component 1110, the configurationcomponent 1120, the non-transitory computer-readable medium 1130, atleast one other component or item disclosed herein, or a combinationthereof function without substantial adverse impact when submerged about350 meter or less (e.g., about 50 meters) underwater (e.g., whensubmerged at a safe depth for human divers).

FIG. 12 illustrates one embodiment of a system 1200 comprising aprocessor 1210 and the non-transitory computer-readable medium 1130. Inone embodiment the non-transitory computer-readable medium 1130 iscommunicatively coupled to the processor 1210 and stores a command setexecutable by the processor 1210 to facilitate operation of at least onecomponent disclosed herein (e.g., the first conversion component 310and/or the second conversion component 320 of FIG. 3). In oneembodiment, components disclosed herein (e.g., the access component 1110and/or the configuration component 1120 of FIG. 11) can be implemented,at least in part, by way of non-software, such as implemented ashardware. In one embodiment the non-transitory computer-readable medium1130 is configured to store processor-executable instructions that whenexecuted by the processor 1210 cause the processor 1210 to perform amethod disclosed herein (e.g., the methods 1300 and 1400 discussedbelow).

FIG. 13 illustrates one embodiment of a method 1300 with two actions1310-1320. At 1310 there is receiving the LF AC signal 280 of FIG. 2.This reception can be performed by the diving glove (e.g., thatcomprises the near-field receiver 360 of FIG. 3) while the diving gloveis underwater and is worn by a diver. At 1320 converting the LF ACsignal 280 of FIG. 2 to a DC voltage (e.g., by way of the DC signal 270of FIG. 2) can occur. The DC voltage can be employed to determine alocation of a base signal (e.g., the signal 120 of FIG. 1) from whichthe LF AC signal 280 of FIG. 2 is based. In one embodiment, the LF ACsignal 280 of FIG. 2 can be received by way of an inductive pickup inthe diving glove, such as from the transmitter 330 of FIG. 3 held by wayof the diving glove when the transmitter 330 of FIG. 3 transmits the LFAC signal 280 of FIG. 2 by way of an inductive transmitter.

FIG. 14 illustrates one embodiment of a method 1400 with four actions1310-1320 and 1410-1420. At 1310 the above-discusses reception can occurand at 1320 the above-discussed conversion can occur. At 1410determining the location of the base signal through employment of the DCvoltage can take place. In one example, the DC voltage can correspond toa direction and/or distance found in a look-up table retained by thediving glove. At 420 there can be causing display of an information setbased, at least in part, on the location in a display (e.g., the eyewearelement 920 of FIG. 9 by way of the directional portion 1010 of FIG. 10)of an underwater mask. In one embodiment, the information set includesproximity information with regard to the location and a line of sightfor a wearer of the mask (e.g., line of sight with regard to the source130 of FIG. 1).

Aspects disclosed herein can be practiced in a variety of environmentsand/or situations. In one example, an airplane can crash over a largebody of water such as the Atlantic Ocean. The source 130 of FIG. 1 canbe an event recorder of the airplane or a piece of equipment worn by thepilot. A mask of the pilot can be configured to function above water aswell as underwater and disclose the heads-up display 1000 of FIG. 10.The mask can provide an indication of where rescue personnel arelocated, thus the source 130 of FIG. 1 can also function as the receiver110 of FIG. 1 depending on the perspective.

In one example, the heads-up display 1000 of FIG. 10 on the mask canaugment radio communication among a dive team and/or help if radiocommunication fails. In this example, text that is spoken can bedisplayed on the heads-up display 1000 of FIG. 10 similar to closedcaptioning. In addition, portions of the heads-up display 1000 of FIG.10 can be used to communicate radio failure information.
